  • IVF in Thailand for Single Women and Same-Sex Couples: A Practical Guide

    Introduction

    Thailand has become a popular destination for fertility treatment, including for single women and same-sex couples. Many clinics offer services tailored to diverse family-building needs. However, legal frameworks, donor options, and clinic policies vary, so careful planning is essential. This guide provides an overview of what to consider when planning IVF in Thailand as a single woman or same-sex couple.

    Legal Considerations

    Thailand’s legal landscape regarding assisted reproduction is complex and evolving. Specific regulations may affect your treatment. Key points to verify with your chosen clinic and a legal advisor include:

    • Parental rights: Confirm how parentage is recognized under Thai law and in your home country.
    • Donor anonymity: Ask clinics about their policies on donor identity disclosure.
    • Embryo status: Understand the legal status of embryos, especially if you plan to freeze, store, or transport them.

    No legal conclusions are provided here. Verify current legal interpretations directly with your clinic and consider consulting a Thai family law attorney.

    Donor Options

    For single women and same-sex couples, donor sperm, eggs, or embryos may be needed. Thailand has both local and international donor options:

    • Sperm donors: Some clinics have their own donor banks or can arrange anonymous or known donors. International sperm banks can also ship to Thailand, but confirm shipping and legal acceptance with the clinic.
    • Egg donors: Egg donation is available, but waiting times and costs vary. Some clinics offer shared donor programs.
    • Embryo donation: Less common, but some clinics may have programs.

    Ask your clinic about donor screening, genetic testing, and legal agreements. If using a known donor, ensure all parties understand their rights and responsibilities.

    Clinic Policies and Selection

    Not all clinics have the same policies regarding single women and same-sex couples. When researching clinics, ask directly:

    • Do you treat single women and same-sex couples?
    • What donor options do you offer?
    • Do you have experience with international patients in similar situations?
    • What are your policies on embryo freezing, storage, and shipping?

    Below is a comparison of several Bangkok fertility centers that may be suitable. The order is editorial and not a ranking of outcomes. Always confirm current services and policies directly.

    Remote Consultation and Documentation

    Most clinics offer remote consultations via video call. Prepare the following:

    • Medical records: previous fertility tests, hormone levels, ultrasound reports, semen analysis (if applicable)
    • Identification: passport copy
    • Legal documents: if using a known donor, a written agreement may be required
    • Questions: prepare a list about treatment protocols, success rates, costs, and policies

    During the consultation, discuss your specific situation openly. The clinic can advise on the best treatment plan and any additional requirements.

    Privacy and Confidentiality

    Privacy practices vary by clinic. Ask about:

    • How your medical and personal data is stored and shared
    • Whether donor information is kept confidential
    • Policies on embryo and gamete storage and disposal

    Choose a clinic that respects your privacy and provides clear written policies.

    Travel Flexibility and Accommodation

    IVF treatment typically requires a stay of 2-4 weeks for the initial cycle, with possible return visits for embryo transfer. Consider:

    • Visa: Check current visa requirements with the Thai embassy based on your nationality.
    • Accommodation: Many clinics offer package deals with nearby hotels or serviced apartments. Alternatively, book your own. Look for places with kitchen facilities for meal preparation.
    • Travel insurance: Ensure your policy covers fertility treatment and any complications.
    • Support person: Consider bringing a friend or partner for emotional support.

    Communication and Language

    Language proficiency varies by clinic. Tips:

    • Confirm that your doctor and coordinator speak English well.
    • Request written instructions in English for medications and procedures.
    • Use translation apps if needed, but rely on clinic-provided interpreters for critical discussions.

    Follow-Up Care After Returning Home

    After treatment, you will need follow-up monitoring. Plan ahead:

    • Arrange with your local doctor or gynecologist to perform blood tests and ultrasounds as advised by the Thai clinic.
    • Ask the clinic for a detailed discharge summary and treatment protocol to share with your local provider.
    • If you become pregnant, your local obstetrician can manage the pregnancy. The Thai clinic may offer remote support.
    • For embryo storage, confirm shipping options if you want to transfer embryos to another country.

  • Can International Patients Do PGT for Sex Selection in Thailand?

    International patients can undergo preimplantation genetic testing (PGT) in Thailand. Whether PGT is used for sex selection depends on the clinic’s policies and current regulations. This article provides an overview of the medical process, legal and ethical considerations, and important questions to ask before proceeding.

    What Is PGT for Sex Selection?

    Preimplantation genetic testing (PGT) is a technique used during in vitro fertilization (IVF) to screen embryos for genetic conditions. PGT can also determine the sex of embryos by analyzing chromosomes. Sex selection refers to choosing embryos of a specific sex for transfer. It is important to understand that PGT is a medical procedure with risks and limitations, and it does not guarantee pregnancy or a healthy child.

    Legal and Ethical Considerations

    Sex selection is restricted or prohibited in many countries due to ethical concerns. In Thailand, regulations may differ, and the practice is not uniformly allowed. Some Thai fertility centers may offer PGT for sex selection for medical reasons (e.g., preventing sex-linked genetic disorders), while others may offer it for family balancing. International patients should be aware that laws and ethical guidelines can change. This article does not provide legal advice. You must consult directly with your chosen clinic and, if needed, a legal expert familiar with Thai reproductive law to understand current regulations and your specific situation.

    Medical Process Overview

    If you are considering PGT for sex selection, the process typically involves:

    • IVF cycle: Eggs are retrieved and fertilized with sperm to create embryos.
    • Embryo biopsy: A few cells are removed from each embryo for genetic testing.
    • PGT analysis: The cells are analyzed to determine chromosomal makeup, including sex chromosomes (XX for female, XY for male).
    • Embryo transfer: One or more embryos of the desired sex are selected and transferred to the uterus.

    Not all embryos may be suitable for transfer, and success rates depend on many factors, including maternal age, embryo quality, and clinic expertise. No clinic can guarantee a specific outcome.

    Questions to Ask Your Clinic

    Before deciding, you should confirm the following directly with any clinic you consider:

    • Does the clinic offer PGT for sex selection for non-medical reasons (e.g., family balancing)?
    • What are the current Thai regulations regarding sex selection, and how does the clinic comply?
    • What is the cost of the full IVF + PGT cycle, including medications, testing, and embryo storage?
    • What is the clinic’s experience with PGT and sex selection? Can they provide success rates specific to your age group?
    • What are the risks of embryo biopsy and PGT?
    • What happens to embryos of the non-preferred sex? Are they discarded, donated, or frozen?
    • Do you need to provide any documentation or meet specific criteria?

    Choosing a Clinic in Thailand

    Several fertility centers in Thailand offer PGT services. Below is an editorial comparison of some providers that may offer PGT. The order is not a ranking of outcomes or quality. You must verify each clinic’s current services, pricing, and legal stance on sex selection directly.

    Important Uncertainties

    Sex selection is a sensitive and evolving area. The following points require human verification:

    • Exact legal status of sex selection in Thailand at the time of your treatment.
    • Whether a specific clinic offers sex selection for non-medical reasons.
    • Costs, which vary widely and may not include medications, additional testing, or travel expenses.
    • Success rates for PGT and live birth, which are not guaranteed and depend on individual factors.

    Next Steps

    If you are considering PGT for sex selection in Thailand, start by contacting clinics directly. Ask for a written quotation and a clear explanation of their policies. You may also want to consult with a reproductive law specialist in Thailand. For more general information, see our FAQ and Guides. If you need assistance, you can contact us for support.

    Frequently asked questions

    Is sex selection legal in Thailand?

    Thailand's regulations on sex selection are not clearly defined in public sources. Some clinics may offer it for medical reasons (e.g., preventing sex-linked disorders) or family balancing, but laws can change. You must confirm the current legal status directly with your chosen clinic and, if needed, a legal expert.

    Can I choose the sex of my baby through PGT in Thailand?

    Some Thai fertility centers may offer PGT for sex selection, but availability varies. You need to ask each clinic directly whether they provide this service for non-medical reasons and under what conditions.

    What is the success rate of PGT for sex selection?

    Success rates depend on many factors, including maternal age, embryo quality, and clinic expertise. PGT itself is highly accurate for determining sex, but it does not guarantee pregnancy or live birth. No clinic can guarantee a specific outcome.

    How much does PGT for sex selection cost in Thailand?

    Costs vary widely. For example, DHC's basic single-cycle medical package is approximately THB 490,000, but this may not include PGT for sex selection, medications, or storage. Always request a detailed written quotation from the clinic.

    What happens to embryos of the non-preferred sex?

    Policies differ by clinic. Some may discard embryos, others may offer donation or long-term storage. You must discuss this with your clinic and understand your options before treatment.

  • PGT-M for Single Gene Disorders in Thailand: A Patient Guide

    What Is PGT-M?

    Preimplantation genetic testing for monogenic disorders (PGT-M) is a technique used during in vitro fertilization (IVF) to identify embryos that carry a specific single-gene disorder. It is designed for couples or individuals who have a known genetic condition and wish to reduce the chance of passing it to their children. PGT-M is not a guarantee of a healthy pregnancy or live birth, and it is not suitable for everyone. The decision to use PGT-M should be made in consultation with a genetic counselor and fertility specialist.

    How PGT-M Differs from PGT-A and PGT-SR

    PGT-M is one of three main types of preimplantation genetic testing:

    • PGT-A (aneuploidy testing) screens embryos for abnormal numbers of chromosomes (e.g., extra or missing chromosomes). It is often used to improve implantation rates and reduce miscarriage risk, especially in older women.
    • PGT-SR (structural rearrangement testing) detects embryos with unbalanced chromosomal rearrangements, such as translocations or inversions, which can cause infertility or miscarriage.
    • PGT-M specifically looks for a single gene mutation that causes a specific inherited disorder, such as cystic fibrosis, sickle cell disease, or Huntington’s disease. It requires prior knowledge of the exact mutation in the family.

    Each test has different indications, limitations, and success rates. Your clinic will help determine which test, if any, is appropriate for your situation.

    The PGT-M Process in Thailand

    1. Genetic Counseling and Testing

    Before starting IVF with PGT-M, you and your partner (if applicable) will undergo genetic counseling and testing to confirm the specific mutation. This may involve blood or saliva samples from affected family members. The results are used to design a personalized test for your embryos.

    2. Probe Development

    A crucial step in PGT-M is creating a genetic probe—a custom laboratory tool that can identify the mutation in embryonic cells. This process, called probe development or assay design, typically takes several weeks. The probe is made using DNA from the family (e.g., from the parents and an affected child or other relatives). In Thailand, experienced genetic laboratories can develop probes for a wide range of single-gene disorders. The time required and cost of probe development vary by clinic and the complexity of the mutation. You should ask your clinic for an estimate of the timeline and fees.

    3. IVF and Embryo Biopsy

    Once the probe is ready, you undergo a standard IVF cycle to retrieve eggs and create embryos. On day 5 or 6 of development, a few cells are gently removed from each embryo (biopsy). These cells are sent to the genetics lab for analysis.

    4. Genetic Analysis

    The lab uses the custom probe to test the biopsied cells for the mutation. Results typically take a few days to a week. Embryos are classified as unaffected (no mutation), affected (carrying the mutation), or inconclusive. Only unaffected embryos are considered for transfer.

    5. Embryo Transfer and Follow-Up

    One or more unaffected embryos are transferred to the uterus. Any remaining unaffected embryos may be frozen for future use. After pregnancy is confirmed, prenatal diagnostic testing (e.g., chorionic villus sampling or amniocentesis) is recommended to confirm the PGT-M result, as embryo testing is not 100% accurate.

    What Conditions Can Be Tested?

    Thailand’s genetic laboratories can develop probes for many single-gene disorders, including autosomal dominant, autosomal recessive, and X-linked conditions. Common examples include cystic fibrosis, spinal muscular atrophy, beta-thalassemia, and Huntington’s disease. However, not all disorders are testable; the mutation must be known and the family must provide sufficient DNA samples. Your clinic can advise on whether your specific condition is eligible for PGT-M.

    Costs and Timeline

    The cost of PGT-M in Thailand includes several components: probe development, IVF cycle, embryo biopsy, genetic testing, and embryo transfer. Probe development is a one-time fee that can range from a few hundred to several thousand US dollars, depending on the complexity. The total cost for a full PGT-M cycle is typically higher than standard IVF. Exact prices vary widely between clinics and are subject to change. You should request a detailed cost breakdown from your chosen clinic.

    The timeline from initial consultation to embryo transfer can take several months. Probe development alone may take 4–8 weeks. IVF stimulation and egg retrieval add another 2–3 weeks, followed by biopsy and testing (1–2 weeks). Planning ahead is essential.

    Alternatives to PGT-M

    PGT-M is not the only option for couples at risk of passing on a genetic disorder. Alternatives include:

    • Prenatal diagnosis (e.g., CVS or amniocentesis) during pregnancy, with the option to terminate an affected pregnancy.
    • Donor gametes (egg or sperm) from a donor without the genetic condition.
    • Preimplantation genetic testing using polar body biopsy (less common).
    • Natural conception with no testing, accepting the risk.

    Each option has medical, ethical, and emotional implications. Genetic counseling can help you weigh the choices.

    Limitations and Risks

    • Not 100% accurate: There is a small chance of misdiagnosis due to technical errors or biological factors (e.g., mosaicism). Confirmatory prenatal testing is strongly advised.
    • No guarantee of pregnancy: PGT-M does not improve the chance of implantation or live birth; it only selects against a specific mutation.
    • Embryo loss: Some embryos may be affected or inconclusive, reducing the number available for transfer.
    • Time and cost: The process is lengthy and expensive, and not all clinics offer PGT-M.
    • Ethical considerations: Some individuals or cultures may have concerns about embryo selection.

    Choosing a Clinic in Thailand

    When considering PGT-M in Thailand, look for a clinic with:

    • Experience in PGT-M and a dedicated genetics laboratory.
    • Clear communication about probe development timelines and costs.
    • Genetic counseling services.
    • Transparent success rates (though these are not directly comparable).

    You can find more information on our PGT in Thailand page, guides, and FAQ.

    Frequently Asked Questions

    Frequently asked questions

    How long does probe development take for PGT-M?

    Probe development typically takes several weeks, often 4–8 weeks, depending on the complexity of the mutation and the laboratory's workload. Your clinic can provide a specific timeline.

    Can PGT-M test for any single gene disorder?

    PGT-M can test for many single-gene disorders, but the specific mutation must be known and the family must provide adequate DNA samples. Some rare or complex mutations may not be testable. Consult your clinic for eligibility.

    Is PGT-M covered by insurance in Thailand?

    Insurance coverage for PGT-M varies. Most international patients pay out-of-pocket. Check with your insurance provider and clinic for details.

    What is the success rate of PGT-M?

    Success rates depend on many factors, including maternal age, embryo quality, and the specific genetic condition. PGT-M does not guarantee a live birth. Ask your clinic for their most recent data.

  • Can I Choose the Sex of My Baby with PGT in Thailand? Legal and Ethical Considerations

    Can you choose the sex of your baby with PGT in Thailand?

    The short answer is: No, not for non-medical reasons. In Thailand, the use of preimplantation genetic testing (PGT) to select an embryo’s sex for family balancing or personal preference is not permitted by law. However, PGT can reveal the sex of embryos as part of medical testing, and in very limited medical circumstances, sex selection may be allowed to prevent serious sex-linked genetic disorders. This article explains the legal framework, ethical considerations, and what you need to know if you are considering PGT in Thailand.

    What does Thai law say about sex selection?

    Thailand’s Medical Council regulations and the Protection of the Embryo and Fetus for Medical Research Act (unofficial translation) prohibit the use of assisted reproductive technology (ART) for sex selection unless there is a clear medical indication. The law aims to prevent gender discrimination and uphold ethical standards in reproductive medicine. While the exact wording may vary, the consensus among Thai fertility specialists is that non-medical sex selection is not allowed.

    This means that even if PGT can determine whether an embryo is XX (female) or XY (male), the clinic cannot use that information to choose which embryo to transfer based on sex alone. The decision to transfer embryos must be based on medical criteria, such as chromosomal normality or absence of a specific genetic disease.

    What is PGT and how does it relate to sex?

    Preimplantation genetic testing (PGT) is a technique used during IVF to screen embryos for genetic abnormalities before transfer. There are different types:

    • PGT-A (aneuploidy screening): Checks for extra or missing chromosomes, which includes the sex chromosomes (X and Y). This test can reveal the sex of the embryo as a byproduct.
    • PGT-M (monogenic disorders): Tests for specific single-gene diseases, such as cystic fibrosis or thalassemia. If the disease is sex-linked (e.g., Duchenne muscular dystrophy), the test may also identify the sex.
    • PGT-SR (structural rearrangements): Detects chromosomal rearrangements like translocations, which may also involve sex chromosomes.

    In all cases, the primary purpose is medical. The sex information is incidental, and clinics are legally bound not to use it for selection unless medically justified.

    When might sex selection be medically allowed?

    There are rare medical scenarios where selecting an embryo’s sex may be permitted:

    • Prevention of sex-linked genetic disorders: For example, if a mother carries a mutation for hemophilia (which primarily affects males), the clinic may select female embryos to avoid the disease.
    • Severe congenital conditions affecting one sex: In some cases, a condition may be so severe that it is considered a medical reason to select against that sex.

    These exceptions require approval from the clinic’s ethics committee and possibly the Thai Medical Council. The decision is made on a case-by-case basis, and the couple must provide medical documentation.

    Ethical considerations

    The ban on non-medical sex selection reflects broader ethical concerns:

    • Gender equality: Allowing sex selection could reinforce gender stereotypes and lead to imbalanced sex ratios.
    • Embryo status: Selecting embryos based on sex treats them as commodities rather than potential life.
    • Social impact: In some cultures, preference for one sex (often male) can lead to discrimination and demographic imbalances.

    Thailand’s approach aligns with many countries, including the UK, Australia, and most of Europe, where non-medical sex selection is prohibited. However, it differs from countries like the United States, where sex selection is generally allowed.

    What if you want to know the sex for family balancing?

    Family balancing—the desire to have a child of a particular sex to achieve a more balanced family—is not considered a medical indication in Thailand. Therefore, it is not a legal basis for sex selection. Some patients may consider traveling to other countries where it is permitted, but that involves different legal and ethical frameworks.

    Questions to ask your clinic

    If you are considering PGT in Thailand and are curious about sex selection, here are important questions to discuss with your fertility clinic:

    • Does your clinic offer PGT-A, PGT-M, or PGT-SR? What are the medical indications?
    • Under what circumstances, if any, does your clinic allow sex selection?
    • What is the process for obtaining ethics committee approval for medical sex selection?
    • Can you tell me the sex of my embryos as part of PGT results? (Note: Some clinics may disclose this information, but they cannot use it for selection.)
    • What are the legal consequences if a clinic is found to be performing non-medical sex selection?

    It is also wise to consult with a legal expert familiar with Thai reproductive law, as regulations can change.

    Alternatives and considerations

    If sex selection is important to you, you may want to explore options in other countries where it is legal. However, be aware of the ethical, legal, and medical implications. Always verify the credentials of any clinic and ensure they follow local laws.

    For patients in Thailand, the focus should remain on the medical benefits of PGT: reducing the risk of genetic disorders and improving the chances of a healthy pregnancy. The sex of the baby is a secondary consideration that, by law, cannot be the primary reason for embryo selection.

    Summary

    • Non-medical sex selection using PGT is illegal in Thailand.
    • PGT can reveal embryo sex as a byproduct, but this information cannot be used for selection.
    • Medical exceptions exist for preventing serious sex-linked genetic diseases, subject to ethics approval.
    • Always confirm current regulations with your clinic and legal advisor.

    Frequently asked questions

    Is it legal to choose the sex of my baby with PGT in Thailand?

    No, it is not legal for non-medical reasons. Thai law prohibits using PGT for sex selection unless there is a medical indication, such as preventing a serious sex-linked genetic disorder.

    Can PGT tell me the sex of my embryos?

    Yes, PGT-A and other forms of PGT can reveal the sex chromosomes, so the sex of each embryo can be known. However, clinics are not allowed to use this information to select embryos for transfer based on sex alone.

    What are the medical exceptions for sex selection in Thailand?

    Sex selection may be permitted to avoid passing on a severe sex-linked genetic disease (e.g., hemophilia, Duchenne muscular dystrophy). This requires approval from the clinic's ethics committee and possibly the Thai Medical Council.

    Can I go to Thailand for IVF and then have sex selection in another country?

    That would involve separate legal and medical processes. You would need to comply with the laws of both countries. It is important to consult with legal experts and clinics in each jurisdiction.

    What should I ask my clinic about sex selection?

    Ask whether they offer PGT, under what conditions they disclose embryo sex, and whether they have ever obtained ethics approval for medical sex selection. Also inquire about the legal framework they operate under.

  • How Does PGT Work in Thailand? A Step-by-Step Guide for International Patients

    What Is PGT and Why Is It Used?

    Preimplantation genetic testing (PGT) is a technique used alongside in vitro fertilization (IVF) to screen embryos for genetic abnormalities before transfer to the uterus. It helps identify embryos with the correct number of chromosomes (PGT-A), specific single-gene disorders (PGT-M), or structural rearrangements (PGT-SR). PGT is not a guarantee of a healthy pregnancy or live birth, and it is not suitable for every patient. Your fertility specialist will help determine if PGT is appropriate based on your medical history and family planning goals.

    Step 1: IVF Cycle and Embryo Development

    The PGT process begins with a standard IVF cycle. You will undergo ovarian stimulation to produce multiple eggs, which are then retrieved and fertilized with sperm in the laboratory. The resulting embryos are cultured for 5–6 days until they reach the blastocyst stage. At this point, the embryo has two distinct cell types: the inner cell mass (which becomes the fetus) and the trophectoderm (which becomes the placenta). Only embryos that develop to the blastocyst stage are suitable for biopsy.

    Step 2: Embryo Biopsy

    On day 5 or 6 of development, a skilled embryologist performs a biopsy. Using a laser and a fine pipette, the embryologist removes 3–5 cells from the trophectoderm. This is done carefully to minimize any impact on the embryo’s viability. The biopsied cells are then sent for genetic analysis. The embryo itself is frozen (vitrified) while awaiting results.

    Step 3: Genetic Analysis

    The biopsied cells undergo genetic testing in a specialized laboratory. The type of analysis depends on the indication:

    • PGT-A (Aneuploidy Testing): Screens for the correct number of chromosomes. Embryos with an abnormal number (aneuploid) are less likely to implant or may lead to miscarriage.
    • PGT-M (Monogenic Testing): Detects specific single-gene disorders such as cystic fibrosis, sickle cell disease, or thalassemia. This requires prior knowledge of the genetic mutation in the family.
    • PGT-SR (Structural Rearrangement Testing): Identifies embryos with balanced or unbalanced chromosomal rearrangements, such as translocations or inversions.

    Thailand follows international standards for genetic testing, and laboratories use validated techniques such as next-generation sequencing (NGS) for PGT-A and polymerase chain reaction (PCR) or NGS for PGT-M and PGT-SR. The analysis typically takes 1–2 weeks, depending on the complexity.

    Step 4: Result Interpretation

    Results are reported as:

    • Euploid: Normal chromosome number (for PGT-A) or unaffected (for PGT-M/SR). These embryos are prioritized for transfer.
    • Aneuploid: Abnormal chromosome number. These embryos are generally not transferred.
    • Mosaic: A mix of normal and abnormal cells. The clinical significance of mosaicism is still being studied, and transfer decisions are made on a case-by-case basis.
    • Inconclusive: The biopsy sample did not yield sufficient DNA for analysis. Re-biopsy may be possible in some cases.

    It is important to discuss results with your genetic counselor or fertility specialist to understand the implications for your specific situation.

    Step 5: Frozen Embryo Transfer

    Once results are available, a euploid or unaffected embryo is selected for transfer. The embryo is thawed and transferred into the uterus in a subsequent menstrual cycle. The timing of the transfer is coordinated with your natural cycle or a hormone replacement protocol.

    Alternatives and Limitations

    PGT is not the only option. Alternatives include:

    • Prenatal testing (chorionic villus sampling or amniocentesis) during pregnancy.
    • Donor eggs or sperm to avoid inherited genetic conditions.
    • Natural conception with genetic counseling.

    Limitations of PGT include:

    • Not all embryos reach the blastocyst stage for biopsy.
    • PGT cannot detect all genetic disorders or guarantee a healthy baby.
    • There is a small risk of embryo damage during biopsy.
    • Mosaic results can be difficult to interpret.

    PGT is a powerful tool, but it is not a guarantee of pregnancy or a healthy child. Discuss all options thoroughly with your medical team.

    What International Patients Should Know

    Thailand has a well-established reputation for fertility care, with many clinics offering PGT services that adhere to international standards. As an international patient, you will need to plan for travel, accommodation, and time in Thailand. The entire process—from initial consultation to embryo transfer—can take several weeks to months, depending on your cycle and testing requirements.

    Key considerations include:

    • Medical records: Bring all relevant medical history, genetic reports, and prior fertility treatments.
    • Legal aspects: Confirm the legal status of PGT for your specific indication (e.g., sex selection may be restricted).
    • Costs: Obtain a detailed cost breakdown from your clinic, including IVF, biopsy, genetic testing, and embryo storage.
    • Support: Consider working with a patient coordinator who can assist with logistics and communication.

    Frequently asked questions

    How long does the PGT process take in Thailand?

    The entire process from IVF stimulation to embryo transfer typically takes 6–8 weeks, but this can vary depending on your cycle, the type of PGT, and laboratory timelines. Confirm with your clinic for an individualized timeline.

    Is PGT legal in Thailand?

    PGT is available in Thailand for medical indications such as preventing genetic disorders. However, regulations may vary, and some uses (like sex selection for non-medical reasons) may be restricted. Always verify current laws with your clinic or legal advisor.

    Can I choose the sex of my embryo with PGT in Thailand?

    Sex selection is generally not permitted for non-medical reasons in Thailand. PGT may be used to avoid sex-linked genetic disorders. Discuss your specific situation with your clinic.

    What is the success rate of PGT in Thailand?

    Success rates depend on many factors including maternal age, embryo quality, and the specific genetic condition. There are no guaranteed outcomes. Ask your clinic for their most recent data relevant to your case.

    Do I need to stay in Thailand for the entire PGT cycle?

    You will need to be in Thailand for egg retrieval and embryo transfer. The genetic analysis takes 1–2 weeks, during which you may return home if you wish, but discuss logistics with your clinic.

  • How to Read Your PGT Results from a Thailand Lab

    Understanding PGT Results

    Preimplantation Genetic Testing (PGT) is a technique used during IVF to screen embryos for genetic abnormalities before transfer. Results from a Thailand lab typically fall into categories such as euploid, aneuploid, mosaic, or inconclusive. This guide explains these terms and what they mean for your next steps.

    Types of PGT

    PGT-A (Aneuploidy Screening)

    PGT-A checks embryos for the correct number of chromosomes. A normal result is called euploid, meaning the embryo has the expected 46 chromosomes. An abnormal result is aneuploid, indicating missing or extra chromosomes. Some embryos show a mix of normal and abnormal cells, known as mosaic. Occasionally, the lab cannot give a clear result, labeled inconclusive.

    PGT-M (Monogenic Disorders)

    PGT-M screens for specific single-gene disorders such as cystic fibrosis or thalassemia. Results indicate whether the embryo carries the disease-causing mutation, is unaffected, or is a carrier (if relevant).

    PGT-SR (Structural Rearrangements)

    PGT-SR detects chromosomal structural changes like translocations or inversions. Results show whether the embryo has a balanced or unbalanced rearrangement.

    Interpreting Your Results

    Euploid

    A euploid embryo has the correct number of chromosomes and is considered chromosomally normal. For PGT-A, this is generally the preferred category for transfer, as it has the highest chance of implantation and a healthy pregnancy. However, euploid does not guarantee a successful pregnancy or a healthy baby.

    Aneuploid

    An aneuploid embryo has an abnormal chromosome count, such as trisomy (extra chromosome) or monosomy (missing chromosome). Most aneuploid embryos will not implant or will miscarry. Some may result in a child with a condition like Down syndrome. Transfer of aneuploid embryos is generally not recommended, but you should discuss all options with your doctor.

    Mosaic

    A mosaic embryo contains both normal and abnormal cells. The proportion of abnormal cells is reported as a percentage (e.g., 20% mosaic). Mosaic embryos may have reduced implantation potential and a small risk of a chromosomal condition. Some clinics consider transfer of low-level mosaics (<20-30%) after counseling. The decision is complex and should involve a genetic counselor.

    Inconclusive

    An inconclusive result means the lab could not determine the embryo’s chromosomal status due to technical issues, such as failed amplification or poor DNA quality. Your doctor may recommend retesting or consider the embryo for transfer after discussing risks.

    What Each Result Means for Transfer Decisions

    • Euploid: Highest priority for transfer. Discuss with your doctor.
    • Aneuploid: Typically not transferred. Confirm with your clinic’s policy.
    • Mosaic: May be considered for transfer if no euploid embryos are available. Requires genetic counseling.
    • Inconclusive: Options include retesting or transfer after counseling. Not all labs offer retesting.

    Limitations of PGT

    PGT is a screening tool, not a diagnostic test. It cannot detect all genetic conditions, and a normal result does not guarantee a healthy baby. Embryo biopsy carries a small risk of damage. PGT is not recommended for everyone; your doctor can help determine if it is appropriate for your situation.

    Alternatives to PGT

    If PGT is not suitable or you prefer not to test, alternatives include prenatal testing (chorionic villus sampling or amniocentesis) during pregnancy, or using donor eggs or sperm. Discuss these options with your fertility specialist.

    Questions to Ask Your Clinic

    • What type of PGT was performed (PGT-A, PGT-M, PGT-SR)?
    • How are mosaic embryos classified and what are your transfer criteria?
    • What is the lab’s inconclusive rate?
    • Do you offer retesting for inconclusive embryos?
    • What genetic counseling is available?

    Additional Resources

    For more information, see our guides on PGT in Thailand and IVF guides, or visit our FAQ page.

    Frequently asked questions

    What does euploid mean in PGT results?

    Euploid means the embryo has the correct number of chromosomes (46) and is considered chromosomally normal. It is the preferred category for transfer.

    Can a mosaic embryo be transferred?

    Yes, some clinics may transfer mosaic embryos, especially if no euploid embryos are available. The decision involves genetic counseling and depends on the level of mosaicism.

    What should I do if my PGT result is inconclusive?

    Discuss with your doctor whether retesting is possible or if transfer of the embryo is an option after counseling. Not all labs offer retesting.

  • IVF in Thailand for Women Over 38: What to Expect with PGT

    What to Expect from IVF with PGT in Thailand When You Are Over 38

    If you are over 38 and considering IVF in Thailand, you may be wondering how preimplantation genetic testing (PGT) fits into your journey. PGT can help identify embryos with the correct number of chromosomes (euploid) before transfer, which is especially relevant as the risk of chromosomal abnormalities (aneuploidy) increases with age. This article explains what you can generally expect, the important distinctions to understand, and the questions you should ask your clinic.

    Age-Related Aneuploidy and Euploid Embryo Rates

    As women age, a higher proportion of eggs and resulting embryos are likely to have an abnormal number of chromosomes. This is a natural biological process. For women over 38, the chance of producing a chromosomally normal (euploid) embryo per egg retrieved is lower compared to younger women. However, individual results vary widely. PGT can help identify which embryos are euploid, potentially increasing the chance of a successful pregnancy per transfer and reducing the risk of miscarriage due to chromosomal abnormalities.

    It is important to have realistic expectations. Not every cycle will produce a euploid embryo, and multiple cycles may be needed. Your clinic can provide personalized estimates based on your ovarian reserve, age, and other factors.

    Key Distinctions: PGT-A vs. PGT-M vs. PGT-SR

    PGT has different subtypes. For older women, the most common is PGT for aneuploidy (PGT-A), which screens for extra or missing chromosomes. PGT-M is for single-gene disorders, and PGT-SR is for structural rearrangements. Discuss with your clinic which type is appropriate for your situation.

    Cycle Planning Considerations

    IVF with PGT in Thailand typically involves the following steps:

    • Ovarian stimulation and egg retrieval
    • Fertilization (usually via ICSI)
    • Embryo culture to blastocyst stage (day 5-6)
    • Biopsy of a few cells from the trophectoderm (future placenta)
    • Vitrification (freezing) of biopsied embryos
    • Genetic analysis (results may take days to weeks)
    • Frozen embryo transfer (FET) of a euploid embryo in a subsequent cycle

    Because PGT requires freezing embryos, you will likely have a delay between retrieval and transfer. Plan for at least two menstrual cycles for a complete PGT cycle.

    Uncertainties and Variables

    No test can guarantee a healthy baby. PGT reduces but does not eliminate the risk of miscarriage or chromosomal conditions. Embryos can be mosaic (a mix of normal and abnormal cells), and interpretation of results can be complex. Additionally, not all embryos survive the biopsy and freezing process. Your clinic should explain the limitations and success rates based on their own data.

    Questions to Ask Your Clinic

    Before proceeding, consider asking:

    • What is your experience with PGT for women over 38?
    • What are the estimated euploid rates for my age group?
    • How many eggs or blastocysts should I aim for to have a reasonable chance of at least one euploid embryo?
    • What is the turnaround time for PGT results?
    • What are the costs for PGT, and are there any package options?
    • How do you handle mosaic embryos?
    • What is your live birth rate per euploid embryo transfer for women over 38?

    Frequently asked questions

    What is the chance of a euploid embryo for a woman over 38?

    The chance varies by individual age and ovarian reserve. Generally, the proportion of euploid embryos declines with age. Your clinic can provide estimates based on your specific situation.

    Does PGT improve the chance of live birth for older women?

    PGT can help select euploid embryos for transfer, which may reduce miscarriage risk and improve per-transfer success rates. However, it does not guarantee live birth, and the overall chance depends on having at least one euploid embryo.

    How long does a PGT cycle take in Thailand?

    A full cycle with PGT typically spans two menstrual cycles: one for egg retrieval and embryo biopsy, and another for frozen embryo transfer after results are available.

  • How to Choose Between PGT-A and PGT-M for IVF in Thailand

    What Are PGT-A and PGT-M?

    Preimplantation genetic testing (PGT) is performed on embryos created through in vitro fertilization (IVF) before transfer to the uterus. Two common types are PGT-A and PGT-M.

    • PGT-A (Preimplantation Genetic Testing for Aneuploidy) screens embryos for abnormal numbers of chromosomes (aneuploidy). It helps identify embryos with the correct chromosome count (euploid), which may have a higher chance of implantation and lower risk of miscarriage due to chromosomal errors.
    • PGT-M (Preimplantation Genetic Testing for Monogenic Disorders) detects specific single-gene disorders, such as cystic fibrosis, sickle cell disease, or Huntington’s disease. It is used when one or both parents carry a known genetic mutation.

    A third type, PGT-SR (Preimplantation Genetic Testing for Structural Rearrangements), identifies embryos with balanced or unbalanced chromosomal rearrangements, such as translocations. This article focuses on PGT-A and PGT-M, as they are the most commonly discussed.

    Key Differences in Purpose and Technique

    Aspect PGT-A PGT-M
    Purpose Screen for chromosome number abnormalities Detect specific single-gene disorders
    Who needs it Often recommended for advanced maternal age, recurrent miscarriage, repeated implantation failure, or severe male factor infertility; also used for any patient wanting to reduce aneuploidy risk Couples known to carry a genetic mutation for a serious inherited condition
    Technique Biopsy of 5–10 cells from the trophectoderm (future placenta) on day 5/6; analyzed by next-generation sequencing (NGS) or array comparative genomic hybridization (aCGH) Same biopsy method; then uses polymerase chain reaction (PCR) or other mutation-specific methods to test for the known mutation
    Result Euploid (normal), aneuploid (abnormal), or mosaic (mixed cell lines) Affected, unaffected (carrier or non-carrier), or inconclusive
    Limitations Cannot detect all genetic disorders; mosaicism can complicate interpretation; does not guarantee pregnancy or live birth Requires prior knowledge of the specific mutation; test must be custom-developed for each family; may have technical limitations

    When Are Both PGT-A and PGT-M Needed?

    In some cases, a couple may benefit from both tests. For example:

    • A woman of advanced maternal age who also carries a BRCA1 mutation may want PGT-A to reduce aneuploidy risk and PGT-M to select embryos without the mutation.
    • A couple with a history of recurrent miscarriage and a known single-gene disorder may use PGT-A to identify chromosomally normal embryos and PGT-M to avoid the inherited condition.

    When both tests are performed, the embryo biopsy is the same, but the genetic analysis includes both aneuploidy screening and mutation detection. This is often called combined PGT or PGT-A+PGT-M.

    Example Scenarios

    Scenario 1: Advanced Maternal Age

    A 40-year-old woman with no known genetic disorders may choose PGT-A to select euploid embryos, potentially improving implantation rates and reducing miscarriage risk. PGT-M is not needed.

    Scenario 2: Known Genetic Mutation

    A couple where both partners are carriers of cystic fibrosis may opt for PGT-M to identify embryos that are unaffected. If the female partner is under 35 with no fertility issues, PGT-A may not be necessary, though some clinics offer it as an optional add-on.

    Scenario 3: Both Indications

    A 38-year-old woman who carries a mutation for Huntington’s disease may choose both PGT-A and PGT-M to maximize the chance of a healthy pregnancy.

    How to Decide: Questions to Discuss With Your Doctor

    Choosing between PGT-A and PGT-M—or deciding to use both—requires careful counseling. Consider asking your fertility specialist and genetic counselor:

    • What is my risk of having an embryo with a chromosomal abnormality or a specific genetic disorder?
    • Does my age, medical history, or family history suggest a benefit from PGT-A?
    • Have I or my partner been tested for carrier status of common genetic conditions?
    • What are the success rates and limitations of each test at the clinic I am considering?
    • How will the results affect embryo transfer decisions?
    • What are the costs and timelines for each test?

    Remember that PGT does not guarantee a pregnancy or a healthy baby. It is a screening tool that can reduce certain risks but cannot eliminate all possibilities of genetic or chromosomal conditions.

    Alternatives and Additional Considerations

    For patients who do not wish to undergo PGT, alternatives include:

    • Prenatal testing (chorionic villus sampling or amniocentesis) during pregnancy to diagnose chromosomal or genetic conditions.
    • Non-invasive prenatal testing (NIPT) for common aneuploidies, though it is a screening test, not diagnostic.
    • Donor eggs or sperm to avoid passing on genetic disorders.
    • Natural conception with or without carrier screening and prenatal diagnosis.

    Each option has its own benefits, risks, and limitations. A genetic counselor can help you weigh these choices based on your personal values and medical situation.

    Next Steps

    If you are considering IVF with PGT in Thailand, start by consulting a fertility clinic that offers comprehensive genetic testing services. Ask about their experience with PGT-A and PGT-M, the laboratory they use, and the counseling support available. For more information, explore our PGT in Thailand overview, guides, and FAQ.

    Frequently asked questions

    Can PGT-A detect all genetic disorders?

    No, PGT-A only screens for abnormal numbers of chromosomes. It does not detect single-gene disorders or structural rearrangements. For specific genetic conditions, PGT-M or PGT-SR is required.

    Is PGT-M always necessary if I am a carrier of a genetic mutation?

    Not necessarily. If the condition is recessive and your partner is not a carrier, the risk of an affected child is low. However, if both partners are carriers, or if you have an autosomal dominant condition, PGT-M may be recommended. Discuss your specific situation with a genetic counselor.

    Can PGT-A and PGT-M be done together?

    Yes, many clinics offer combined PGT (PGT-A+PGT-M) using the same embryo biopsy. This allows screening for both chromosomal abnormalities and a specific genetic mutation.

    Does PGT guarantee a healthy baby?

    No. PGT reduces the risk of transferring embryos with certain chromosomal or genetic abnormalities, but it cannot guarantee a pregnancy, live birth, or a child free from all health conditions. Some abnormalities may not be detectable, and there is always a small risk of misdiagnosis.

  • PGT-M for Single Gene Disorders in Thailand: Process and Cost

    What Is PGT-M?

    Preimplantation Genetic Testing for Monogenic disorders (PGT-M) is a technique used during IVF to identify embryos that carry a specific single gene disorder. It is designed for couples where one or both partners are known carriers of a genetic condition, such as cystic fibrosis, Huntington’s disease, or thalassemia. PGT-M allows embryologists to biopsy embryos and test them for the specific mutation before transfer, with the goal of selecting embryos that are unaffected.

    It is important to understand that PGT-M does not guarantee a pregnancy or a healthy child. It is a screening tool that reduces the risk of passing on a known genetic condition, but it cannot detect all possible genetic abnormalities or ensure embryo viability.

    PGT-M vs. Other PGT Types

    PGT-M is distinct from PGT-A (aneuploidy testing) and PGT-SR (structural rearrangement testing). PGT-A screens for abnormal numbers of chromosomes, while PGT-SR detects chromosomal structural changes. PGT-M focuses specifically on single gene mutations. Some clinics may offer combined testing, but this should be discussed with your provider.

    The Process of PGT-M in Thailand

    1. Pre-Testing and Genetic Counseling

    Before starting PGT-M, you must have a confirmed genetic diagnosis. This typically requires genetic reports from a certified laboratory showing the specific mutation(s) in the carrier(s). Many clinics require a genetic counseling session to discuss inheritance patterns, testing limitations, and implications for the child.

    2. Probe Development

    PGT-M requires a customized genetic probe for your family’s mutation. This is a laboratory process where markers linked to the mutation are identified. Probe development can take several weeks to months, depending on the complexity of the mutation and the laboratory’s workload. Some clinics may have pre-validated probes for common mutations, which can shorten the timeline.

    You will need to provide blood samples from both partners and, if available, from an affected child or other family members. The probe is then validated before it can be used on embryos.

    3. IVF Cycle and Embryo Biopsy

    Once the probe is ready, you proceed with an IVF cycle. Ovarian stimulation, egg retrieval, and fertilization are performed as usual. Embryos are cultured to the blastocyst stage (day 5 or 6), and a few cells are biopsied from the trophectoderm (future placenta). The biopsy is then sent to the genetics laboratory for analysis.

    4. Genetic Analysis and Embryo Selection

    The laboratory uses the custom probe to test each embryo for the mutation. Results typically take 1–2 weeks. Embryos are classified as unaffected (free of the mutation), affected (carrying the mutation), or inconclusive. Only unaffected embryos are considered for transfer.

    5. Embryo Transfer and Follow-Up

    A frozen embryo transfer (FET) is usually performed in a subsequent cycle. After transfer, prenatal diagnosis (e.g., chorionic villus sampling or amniocentesis) is recommended to confirm the genetic status of the pregnancy, as PGT-M is highly accurate but not 100%.

    Timeline Overview

    The entire process from initial consultation to embryo transfer can take 4–8 months or longer. Key steps include:

    • Genetic counseling and report review: 1–2 weeks
    • Probe development: 4–12 weeks (or longer for rare mutations)
    • IVF cycle (stimulation to biopsy): 4–6 weeks
    • Genetic analysis: 1–2 weeks
    • Frozen embryo transfer: 4–8 weeks after analysis

    These are general estimates; actual timelines vary by clinic and individual circumstances.

    Cost Considerations

    The cost of PGT-M in Thailand varies widely depending on the clinic, the complexity of the probe, and the number of embryos tested. Typical cost components include:

    • Genetic counseling and report review fees
    • Probe development fee (often a one-time cost per mutation)
    • IVF cycle costs (medications, monitoring, egg retrieval, lab fees)
    • Embryo biopsy fee
    • PGT-M analysis fee per embryo
    • Embryo freezing and storage fees
    • Frozen embryo transfer cycle costs

    Some clinics offer package prices that include multiple cycles or a set number of embryos. It is essential to request a detailed cost breakdown from your chosen clinic. Prices are typically quoted in Thai baht or US dollars, and payment plans may be available.

    Because exact figures are time-sensitive and clinic-specific, we recommend contacting clinics directly for current pricing.

    Required Documents and Preparations

    To begin the PGT-M process, you will need:

    • Genetic test reports confirming the mutation(s) in the carrier(s)
    • Medical records related to your fertility and general health
    • Blood samples from both partners (and possibly affected family members) for probe development
    • Passports and visas for travel to Thailand (if applicable)

    Confirm with your clinic whether they require original documents or certified translations.

    Questions to Ask Your Clinic

    • What is the estimated timeline for probe development and the full cycle?
    • What is the cost of probe development, and is it refundable if the cycle is canceled?
    • How many embryos are typically needed for a reasonable chance of an unaffected embryo?
    • What is the accuracy rate of PGT-M for our specific mutation?
    • Do you offer combined PGT-A and PGT-M testing? What are the pros and cons?
    • What happens if no unaffected embryos are available?
    • What prenatal testing do you recommend after a PGT-M pregnancy?

    Limitations and Risks

    PGT-M is not foolproof. Risks include:

    • No embryos may be unaffected, especially if the carrier is homozygous or if few embryos are produced.
    • Inconclusive results may occur, requiring additional testing or discarding the embryo.
    • Mosaicism (mixed cell lines) can complicate interpretation.
    • Biopsy may damage the embryo, though the risk is low with experienced labs.
    • PGT-M does not test for all genetic disorders; only the specific mutation is analyzed.

    It is crucial to have realistic expectations and discuss all options with your genetic counselor and fertility specialist.

    Alternatives to PGT-M

    If PGT-M is not suitable or available, alternatives include:

    • Prenatal diagnosis (CVS or amniocentesis) during a natural pregnancy, with the option to terminate if affected.
    • Donor gametes (egg or sperm) from a non-carrier.
    • Preimplantation genetic testing using polar body biopsy (less common).
    • Adoption or remaining child-free.

    Each option has its own ethical, emotional, and practical considerations.

    For more information, explore our PGT in Thailand overview, patient guides, and frequently asked questions.

    Frequently asked questions

    How long does PGT-M probe development take in Thailand?

    Probe development typically takes 4 to 12 weeks, but can be longer for rare or complex mutations. Some clinics have pre-validated probes for common mutations, which can reduce the time. Confirm the estimated timeline with your chosen clinic.

    What genetic reports are needed for PGT-M?

    You need a confirmed genetic diagnosis from a certified laboratory showing the specific mutation(s) in the carrier(s). Reports should include the gene name, mutation details, and inheritance pattern. Some clinics also require reports from affected family members for probe validation.

    Is PGT-M covered by insurance in Thailand?

    Insurance coverage for PGT-M is rare and varies by policy. Most patients pay out-of-pocket. Check with your insurance provider and clinic for any possible reimbursement or package deals.

    Can PGT-M be combined with PGT-A?

    Yes, many clinics offer combined PGT-A and PGT-M testing on the same biopsy. This screens for both chromosomal abnormalities and the specific single gene disorder. Discuss the additional cost and potential benefits with your clinic.

    What happens if all embryos are affected?

    If no unaffected embryos are available, options include using donor gametes, considering prenatal diagnosis in a future natural pregnancy, or exploring adoption. Your clinic and genetic counselor can help you explore alternatives.

  • PGT for Chromosomal Abnormalities in Thailand: A Guide for Patients

    What Is Preimplantation Genetic Testing (PGT)?

    Preimplantation genetic testing (PGT) is a technique used during in vitro fertilization (IVF) to screen embryos for genetic or chromosomal abnormalities before transfer. It is not a guarantee of a healthy pregnancy or live birth, but it can help select embryos with a lower risk of certain conditions. In Thailand, PGT is available at several fertility centers, and the technology is broadly divided into three main types: PGT-A, PGT-M, and PGT-SR.

    PGT-A: Testing for Aneuploidy

    PGT-A (preimplantation genetic testing for aneuploidy) screens embryos for an abnormal number of chromosomes, known as aneuploidy. Humans typically have 46 chromosomes (23 pairs). An extra or missing chromosome can lead to conditions such as Down syndrome (trisomy 21) or Turner syndrome (monosomy X), and often results in implantation failure or miscarriage.

    How PGT-A Works

    During an IVF cycle, embryos are cultured for 5–6 days until they reach the blastocyst stage. A few cells are biopsied from the trophectoderm (the outer layer that becomes the placenta) and sent for genetic analysis. The embryo is then frozen while the results are processed. PGT-A uses techniques such as next-generation sequencing (NGS) or array comparative genomic hybridization (aCGH) to count the chromosomes.

    Who Might Consider PGT-A?

    PGT-A is often recommended for patients with:

    • Advanced maternal age (typically 35 or older)
    • Recurrent miscarriage (two or more pregnancy losses)
    • Previous aneuploid pregnancy
    • Severe male factor infertility
    • Repeated IVF failure

    However, not all patients need PGT-A. Younger patients with no history of miscarriage or genetic disorders may have a low risk of aneuploidy, and the added cost and procedure may not be justified. Discuss your individual risk factors with your fertility specialist.

    Understanding PGT-A Results

    Results are reported as:

    • Euploid: Normal number of chromosomes. These embryos have the highest chance of implantation and a healthy pregnancy.
    • Aneuploid: Abnormal number of chromosomes. These embryos are unlikely to result in a live birth and are typically not transferred.
    • Mosaic: A mix of normal and abnormal cells. Mosaic embryos may have reduced potential, but some can still lead to healthy pregnancies. The decision to transfer a mosaic embryo should be made with genetic counseling.

    It is important to note that PGT-A cannot detect all genetic disorders, and a euploid result does not guarantee a healthy baby.

    PGT-SR: Testing for Structural Rearrangements

    PGT-SR (preimplantation genetic testing for structural rearrangements) is designed for patients who carry balanced chromosomal rearrangements, such as translocations or inversions. These individuals have a normal total amount of genetic material but have chromosomes that are rearranged. While they are usually healthy, they are at increased risk of producing embryos with unbalanced rearrangements, which can lead to miscarriage or birth defects.

    How PGT-SR Works

    The process is similar to PGT-A: embryos are biopsied at the blastocyst stage, and the cells are analyzed to determine whether the chromosomal rearrangement is balanced or unbalanced. PGT-SR often uses the same technology as PGT-A (e.g., NGS) but with specialized analysis to detect the specific rearrangement.

    Who Might Consider PGT-SR?

    PGT-SR is typically offered to:

    • Individuals or couples known to carry a balanced translocation or inversion
    • Patients with recurrent miscarriage or a history of a child with an unbalanced rearrangement

    If you have a known chromosomal rearrangement, genetic counseling can help you understand the risks and whether PGT-SR is appropriate.

    Understanding PGT-SR Results

    Results indicate whether the embryo has:

    • Balanced (normal or balanced carrier): The embryo has a normal chromosome structure or carries the same balanced rearrangement as the parent. These embryos are suitable for transfer.
    • Unbalanced: The embryo has extra or missing genetic material due to the rearrangement. These embryos are unlikely to result in a healthy pregnancy and are typically not transferred.

    As with PGT-A, PGT-SR cannot detect all genetic issues, and a balanced result does not guarantee a healthy baby.

    PGT-M: Testing for Monogenic Disorders

    PGT-M (preimplantation genetic testing for monogenic disorders) is used to detect single-gene disorders such as cystic fibrosis, sickle cell disease, or Huntington’s disease. It is relevant for patients with a known genetic mutation in the family. PGT-M requires a custom test to be developed for each family, which takes time and additional cost. While not directly about chromosomal abnormalities, PGT-M may be combined with PGT-A or PGT-SR in some cases.

    Limitations and Considerations

    PGT is a powerful tool but has important limitations:

    • Not 100% accurate: There is a small risk of misdiagnosis due to mosaicism, technical error, or contamination.
    • Embryo biopsy risk: Although rare, the biopsy procedure may damage the embryo.
    • No guarantee of pregnancy: Even a euploid embryo may fail to implant or miscarry due to other factors.
    • Cost: PGT adds significant expense to an IVF cycle. In Thailand, costs vary by clinic and the number of embryos tested. Confirm exact pricing with your chosen clinic.
    • Time: Testing takes several weeks, so embryos must be frozen and transferred in a subsequent cycle.

    Alternatives to PGT

    For some patients, alternatives may be considered:

    • Prenatal testing: Chorionic villus sampling (CVS) or amniocentesis during pregnancy can diagnose chromosomal abnormalities, but these tests carry a small risk of miscarriage and cannot be used to select embryos.
    • Donor eggs or sperm: Using gametes from a screened donor can reduce the risk of chromosomal abnormalities, especially in cases of advanced maternal age or known genetic disorders.
    • Natural conception with genetic counseling: Some couples may choose to conceive naturally and undergo prenatal testing, accepting the risk of miscarriage or affected pregnancy.

    Your fertility specialist can help you weigh the options based on your medical history and personal values.

    What to Discuss with Your Clinic in Thailand

    When considering PGT in Thailand, ask your clinic about:

    • Which types of PGT are offered (PGT-A, PGT-SR, PGT-M)
    • The laboratory’s experience and accreditation
    • Costs for biopsy, testing, and embryo freezing
    • Turnaround time for results
    • Success rates for PGT cycles (note: these vary widely and should be interpreted cautiously)
    • Genetic counseling services

    Frequently asked questions

    What is the difference between PGT-A and PGT-SR?

    PGT-A screens for an abnormal number of chromosomes (aneuploidy), while PGT-SR detects unbalanced structural rearrangements like translocations. PGT-A is used for general aneuploidy risk, and PGT-SR is for patients with known balanced rearrangements.

    Who should consider PGT for chromosomal abnormalities?

    Patients with advanced maternal age, recurrent miscarriage, previous aneuploid pregnancy, or known chromosomal rearrangements may benefit. However, not everyone needs PGT; discuss your specific situation with a fertility specialist.

    Can PGT guarantee a healthy baby?

    No. PGT reduces the risk of transferring embryos with certain chromosomal abnormalities, but it cannot detect all genetic conditions, and there is still a chance of miscarriage or other complications.

    How long does PGT take in Thailand?

    After embryo biopsy, results typically take 1–2 weeks. Embryos are frozen while waiting, so transfer occurs in a later cycle. Confirm exact timelines with your clinic.

    What are the risks of embryo biopsy?

    The biopsy is generally safe, but there is a small risk of embryo damage or reduced viability. The procedure is performed by experienced embryologists to minimize risk.
